IMPROVEMENT IN DEVICES FOR DISPENSING SIRUP IN SODA-WATER APPARATUS.

Specification forming part of Letters Patent No. 141,229, dated July 29,1873; application fled June 24, 1873.

To all whom t may concern:

`Be it known that I, JOHN MATTHEWS, of the city, county, and State ofNew York, have invented certain new and useful Improvements in Devicesfor Dispensing Sirup in Soda-Water Apparatus; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanyingdrawings, which form part of this specification, in which- Figure l is alongitudinal vertical section; Fig. 2, a cross-section; and Fig. 3, aperspective view of the outer port-ion.

T he same letters refer to like parts in all the figures.

In the better class of soda-water apparatus as now constructed thesirup-holders are placed within the ice-chambers or coolers, so as to Ycool thc sirup; but to draw the sirup as required the faucet-stem mustproject beyond the case, and as only a small quantity of sirup sucientfor one glass of soda-water is drawn at a time only about the portionstanding in the outer stem of the faucet is used, and that from itsexposure without the case becomes soon warm, so that warm and not coolsirup is dispensed.

My invention relates to certain improvements in the sirup-draftapparatus and the method of attaching it to the case 5 and consists inmeans for keeping the sirup cool till it is discharged into the glass;in devices for attaching the draft apparatus to the walls of thesirup-tanks; in devices for attaching the label 'to each sirup-faucet;in a construction of the draft-tube and valve whereby the necessity of astuffing-box is avoided, and by which great simplicity of constructionis secured; in means by which the usual wear on the valve is avoided; ina non-metallic plug-valve and a lining of the draft-tube, so as to avoidcorrosion and contamination of the sirup; in an arrangement ot' ports sothat if any leakage occur the drip or leakage will be conveyed to nearthe discharging-port and not to the handle or knob; in a form ofdischarge-port by which the sirup is more rapidly dispensed 5 and,lastly, in means by which the plug-valve is attached to the knob orhandle by which it is operated.

The following description will enable those skilled in the art to makeand use my invention.

In the drawing, a is the body of the faucet havin g within it theannular valve-seat a composed of leather or other suitable soft packingmateria-1. It is a screw-thread on the end of the faucet on the outside.b is a cap or knob having within it a screw-thread tting over thescrew-thread h. c is a plug or valve composed of glass, ceramic ware, orother suitable material, the plug being provided with a shoulder, w 5v,to fit upon the valve-seat n n. This plug c has a portion, y, whichprojects up along the body of the faucet, so that when it is pushed soas to close its shoulder upon the valve-seat a, the portion y willnearly fill the body of the faucet, and prevent any sirup from comingforward so as to leave the cooling medium and become warm by standingoutside the cooling-chamber. z is a projecting collar or ring on theknob ofthe faucet near the discharge-port. g is the discharge-port ofthe faucet. t is a collar on the faucet which is drawn against theapparatus by the nut d ou screw-thread r. j is a feather or key on thebody of thefaucet to keep itfrom turuin ground in the apparatus. f f areribs or projections to fit the hole into which the faucet is screwed.

p p is a washer to pack the joint. q, a section.

of the side of the apparatus into which the faucet is secured. e is awasher serving as a seat for the nut d, and as a label for the name ofthe sirup to be dispensed. o o, passage-way for the sirup through thebody of the faucet with an elbow at t, upturned to receive thesirup-tank. 7c k is a rubber or other elastic collar to pack the jointat the junction with the sirup-tank. I make the inlet-passage m to thefaucet of smaller capacity than the discharge-port g, so that all thesirup entering the cock can be discharged through the discharge-portwithout being forced beyond it into the cap.

The following is the mode of operation: The faucet, after withdrawingthe knob b and nut d, is inserted into a hole in the apparatus of thediameter of the screw-thread' h h, so that the rubber washer is pressedby the collar t'. The washer-plate e is passed over the screwthreads hand r, so as to rest against the sides of the apparatus. The nut d isthen screwed on so as to draw the collar i against the Wash er p p,making a tight joint. The sirup-tank may then be attached to the inletof the faucet m, and the valve-plug inserted and screwed up by the capb, so that the shoulder of the plug presses against the seat a. Thesirup may then be poured into the tank.

To dispense the sirup the cap b should be unscrewed about half a turnwhen the sirup will How through the port g. It' any sirup should escapepast the valve-seat so as to run into the cap, it will drop from thecollar z of the cap near the discharge-port, and will thus not soil thehand of the operator.

This construction dispenses with a stuffingbox, and is of greatsimplicity and durability. The valve-plug being of porcelain or othernoncorrodible material prevents all Wear of the apparatus andcontamination ofthe sirup. The extension y of the plug displaces a largeportion of the sirup Which would otherwise stand outside of theapparatus and become Warm by being removed too far from the coolingmedium. This valve-plug is secured to the knob by having the met-al ofwhich it is composed cast around the plug, which is made with collars orindentations to cause it to be securely held in the metal.

The discharge-port g is in the form of transverse slit, as plainly shownin Fig. 3, so as to require only a slight movement of the valveplug tocompletely expose the opening.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

l. The valve-plug c provided with an extension, y, in combination withthe faucet, so as to drive the sirup out of the forward portion, as andfor the purpose `set forth.

2. The cap b provided with an internal screw and external collar, z, incombination with the faucet, as set forth.

3. The cap b provided with screw-threads, in combination with thevalve-plug 0 and faucet a, arranged and operated as set forth.

4. The plate e With opening, so as to slip over the stem and form awasher with an upward-projectin g portion for a label, in combinationwith the faucet, provided with collar t' and nut el, as set forth.

5. The faucet provided with the dischargeport g of an elongated form,transverse to the length of the faucet, so as to be entirely opened by aslight movement of the valve-plug, in combination with said plug.

In testimony that I claim the foregoing I have hereunto set my hand this24th day of May, 1873.

JOHN MATTHEWS.
